项目摘要
This award provides travel support for 25 students, postdoctoral fellows, and early-career faculty from US institutions to attend the US Association for Computational Mechanics (USACM) Special Topic Conference “Quarter Century of Peridynamics” (PD25), which will be held 22-25 April 2024 in Tucson, Arizona. The main objective of the conference is to broaden the exposure of peridynamics (PD) modeling and simulation to a larger audience that may benefit from the advantages this approach provides to complex, previously unsolvable problems in science, engineering, and technology. Graduate students, post-docs, and participants from industry, national labs, and national agencies will be trained through their participation in the conference and associated short courses. The conference presents an ideal opportunity for networking to early career researchers specializing in modeling and simulation of material degradation and failure, and ways to reduce it (when protecting against damage is sought) or enhance it (as is needed in mining, recycling of materials, etc.). The conference organizers have sought to broaden participation from members of underrepresented groups and undergraduate students who aspire to learn more about PD modeling. These efforts will grow the pipeline of US researchers working on modeling and simulation of material failure and damage.Peridynamics (PD) was introduced in 2000 as a model of fracture and failure in materials and has recently experienced explosive growth in terms of the number of publications and research groups working on PD-related topics. PD is now reaching a broad range of research areas beyond fracture, including modeling of corrosion damage, growth of tumors, electromigration, simulating crushing of powders for medical tablets, and modeling of graphene layers. The major focus of PD modeling and simulation is reliability and safety of mechanical, civil, and aerospace systems, with a direct impact on reducing costs and improving performance of such systems. These effects have a direct impact on health, quality of life, and homeland security. The conference program includes three short courses, running in parallel, on different aspects of PD-based computational software applied to predicting fracture and damage in a variety of materials, including glass and ceramics, metals, and fiber-reinforced composites. These courses, presented by leaders on PD modeling and simulation, aim to provide participants with hands-on experience with PD solvers in a variety of settings, including running massively parallel computations, or coupling with commercial software like ANSYS and Abaqus.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
该奖项为来自美国机构的25名学生、博士后研究员和早期职业教师提供差旅支持,参加美国计算力学协会(USACM)专题会议“近动力学的四分之一世纪”(PD 25),该会议将于2024年4月22日至25日在亚利桑那州图森举行。会议的主要目标是扩大对更多观众的近距离(PD)建模和模拟的曝光,这些观众可能会受益于这种方法为科学,工程和技术中复杂的,以前无法解决的问题提供的优势。研究生,博士后,以及来自行业,国家实验室和国家机构的参与者将通过参加会议和相关的短期课程进行培训。会议为专门从事材料降解和失效建模和模拟的早期职业研究人员提供了一个理想的机会,以及减少材料降解和失效的方法(当寻求保护免受损害时)或增强材料降解和失效的方法(如采矿,材料回收等所需)。会议组织者试图扩大代表性不足的群体成员和渴望更多地了解PD建模的本科生的参与。这些努力将增加美国研究人员在材料失效和损伤的建模和模拟方面的工作。周向断裂力学(PD)于2000年作为材料断裂和失效的模型引入,最近在PD相关主题的出版物和研究小组的数量方面经历了爆炸性增长。PD现在已经扩展到骨折以外的广泛研究领域,包括腐蚀损伤建模、肿瘤生长、电迁移、模拟药物片剂粉末的破碎以及石墨烯层建模。 PD建模和仿真的主要焦点是机械,民用和航空航天系统的可靠性和安全性,对降低成本和提高此类系统的性能有直接影响。这些影响直接影响健康、生活质量和国土安全。会议计划包括三个短期课程,并行运行,在基于PD的计算软件的不同方面应用于预测各种材料的断裂和损伤,包括玻璃和陶瓷,金属和纤维增强复合材料。这些课程由PD建模和仿真领域的领导者主讲,旨在为参与者提供在各种环境下使用PD求解器的实践经验,包括运行大规模并行计算,或与ANSYS和Abaqus等商业软件耦合。该奖项反映了NSF的法定使命,并通过使用基金会的智力价值和更广泛的影响审查标准进行评估,被认为值得支持。
